This answer was rated:

I have a 5 year old lg dryer. See resettable high limit fuse on the side of the moment keeps popping Since I had to change the board. Is it more likely that this part is going bad or that my new board(or other componant) is allowing too much heat ..& Is there a way to test either one ?

Perfect, how often does the resettable fuse trip? Does the fuse trip. If you run this on air dry with no heat?

Twice now ..... just after a 1 load or 2.. I'm going to reset it again now I can run it on air and see if it trips
Yes, that's a good idea, we need to see whether the heat is tripping. It. Have you checked your vent real good? Is it clear and blowing outside real good? Let me know, thanks, Bryan

I ran into on air for a few minutes and then turned the heat on ... it does heat.... the vent is clear and seems to be blowing pretty steady and well

That fuse popped again. I had it on diagnostic mode and the hottest it got was 28 degrees celsius
Okay sounds to me like you need to replace the fuse itself, the fuses weak and is tripping to easily at a lower temperature than it should. It's called the high limit thermostat, you can order this for like $10 at the following link. the only thing I ask of you is to please rate me with one of the top 3 ratings. If there is anything else I can help you with today just let me know. You can continue asking questions for as long as you like even after you rate me.

If you are done rather than rating me with a 1 or 2 smiley faces please use the (continue conversation) link and tell me what else I can do or what else you would like to know so that I can get you that information so I can improve my customer satisfaction rating.
